I am absolutely fascinated by evil. I watch and read true crime constantly - I am somewhat obsessed.
I thought this needed a new thread because it would derail the violence against women thread and besides, only a tiny fraction of "male violence" is murder and rape combined.
I agree with the premise that Wayne Couzens probably is a serial killer and I have quite a few reasons for it. First and formost, he's 48. It's rare for a person to graduate to such a huge, well planned crime without lots of other related crimes in the past. I'd expect not just flashing but also rape (of more than one of the many kinds of rape there are), I'd expect a general pattern of misogyny but not necessarily a history of domestic violence. When the murderer's partner is not the one murdered it raises a lot of red flags (I am not saying it is fine to murder your partner

Serial killers tend to start in their early-mid 20s and they start out being crap at what they do. Wayne Couzens was not crap at what he did by the time he was 48 - it's just dumb luck the police got him on CCTV. He's obviously forensically aware and has been at least since he joined the police, in fact, he's shown a tendency over the course of his career to choose jobs where he has had power over people. He chose to dump the body 50 miles away from the kidnap scene, and lives another 25 miles further than there. They had to identify her via dental records despite the fact she was found only what... 10 days after she disappeared? That implies burning, dismemberment or another means was used to speed up decay. That speaks to someone who knows what he's doing. I highly doubt he'd have used the same disposal method or location twice, he's clearly far too intelligent for that.
I've had a shufty around missing people pages and there are indeed women missing in the South-East and London that fit the profile - I only found about 3 but that proves nothing! If he is a serial killer and he hunted in London he'd have a captive audience of women who wouldn't be missed. He had the ideal kidnap strategy, the tools, the power and the proclivity.
He's definitely done more than one - I'd bet my own actual money on it*. He won't be particularly prolific I don't think - not sure why I say that, it's just a gut feeling. I reckon... he's 48... he's maybe done 6 or 7. I hope he only did the one but... I've read way too much on the subject to be hopeful.
I'm sure the experts are on it (I wish I was one of them
